Earth and its neighbors orbit the sun on a relatively flat plane. But what's below this plane, and is anythign below the ...

Astronomers have, for the first time, captured a detailed snapshot of planetary systems in an era long shrouded in mystery.

A decade of observations of four planets around the young planetary system V1298 Tau revealed a rare, long-sought missing ...

In theory, a planet may be able to orbit a binary star system in a figure of eight, but it may not be particularly stable, ...

— -- Goldilocks, like most fairy tales, offers children a lesson and a happy ending. Whether a Goldilocks planet offers astronomers something similar still hangs up in the air, with the story's ...

A new study has challenged a popular explanation for the unexpected 30-second shortening of Dimorphos's orbital period. The researchers found that the proposed mechanism would actually produce the ...

Scientists measured mass and distance of free floating planet drifting through space without star for first time.

Because their orbits are unstable, a possibility exists that the asteroids could break off from their current trajectory and one day head on a collision course for Earth. The Venusian space rocks are ...

This illustration shows an exoplanet orbiting around two brown dwarfs –– objects bigger than gas-giant planets but too small to be proper stars. ESO/M. Kornmesser Astronomers have discovered a ...

Planet formation used to sound straightforward: dust clumps into rocks, rocks grow into worlds, and the rest is detail. A ...
